Mini MEMS North seeker for Heading machine
Introduction
The ER-MNS-04C MEMS north seeker adopts the latest MEMS gyro technology, breaking through the volume and performance limitations of traditional directional equipment, compressing the volume to the extreme, meeting the integrated operation requirements, and can be easily embedded in various small devices or complex systems. By sensing the horizontal component of the earth's rotation angular velocity, the true north direction can be measured without relying on an external reference benchmark, providing a high-precision azimuth benchmark for complex environments.
It adopts three-axis MEMS gyroscope and three-axis MEMS accelerometer strapdown inertial measurement technology, embedded with the original "Chinese tripod" structure inner platform, through the all-solid-state non-moving parts design and high-density packaging, it has strong stability, can withstand strong impact and vibration, and stably output reliable north-seeking data in complex environments.
Modular design, support flexible OEM customization, compatible with mainstream communication interfaces, and meet the needs of rapid embedding in different scenarios. It is mainly used in mining, tunnel construction, underground space construction and other scenarios.
